EN ISO 11925 Direct Impingement Building Material Flammability Tester (RT-729)
Testing Principles
This experiment determines the combustibility of a specimen in the vertical direction when it encounters a small flame at the edge or surface of the specimen. Observe the combustion behavior of the sample to determine if the flame spreads and if any burning particles or droplets are present.
Product Details：
This product is mainly used for testing the combustion performance of external wall insulation systems and building materials, and as a testing instrument to determine whether building materials are combustible. Production enterprises, relevant quality inspection departments and units, universities, and research institutes are used for heat-resistant and insulation materials.

Product Advantages
Test sample
The sample should represent the final use of the product as much as possible. This is particularly applicable to the use of standard substrates as described in EN 13238. Basic flat specimens should be used: Size: 250mm x 90mm, Thickness: up to 40mm (including substrate used during use). Product standards for specific products (groups) may include provisions for sample structure to achieve maximum application range. Can guide more product samples. After confirming the order in writing and debugging the samples according to the standards, testing can begin.
Additional testing of multi-layer specimens
For multi-layer specimens with a thickness greater than 10 millimeters, only single-layer specimens with a thickness greater than 3 millimeters (excluding adhesive layers) require additional flame impact testing.
